The investigation of war crimes has proved to be a challenging task for the Defence at the International Criminal Tribunal for the former Yugoslavia (ICTY). At the Court’s infancy, civil trained defence counsel with no experience in adversarial party-driven procedures were unfamiliar with aspects of case preparation and trial advocacy, such as gathering evidence by conducting their own investigation, or cross-examination through leading questions based on a coherent theory of the case. These adversarial modalities also came with specific ethical duties. This chapter offers some practical advice and best practices relevant to Defence Counsel practising in national jurisdictions of the former Yugoslavia region and elsewhere, where adversarial modalities similar to those found in the ICTY procedure have been adopted in reforming their criminal procedures—transitioning them from civil law to a more hybrid system.

Multi-component sol–gel derived alumina and titania hybrid materials are assembled by the functionalization of both lanthanide complexes and a special metal organic framework compound: Al-MIL-53-COOH through coordination bonds. Multi-color luminescence and white colored light can be tuned by controlling the different units in the hybrid system.

This paper introduces a fluidic technique based on patterned shapes of hydrophobic self-assembly monolayers (SAMs) and capillary forces to self-assemble micro-parts onto substrates. Self-assembly is defined as a spontaneous process that occurs in a statistical, non-guided fashion. More specifically, the fluidic self-assembly with capillary force is driven by the gradient in interfacial free energy when a micro-part approaches a substrate binding site. In this paper, the mechanism of self-assembly with capillary forces is proposed. The hydrophobic-hydrophilic material system between the binding sites and micro-parts is then simulated. Finally, the surface energy of a self-assembling system in the liquid phase under different conditions is calculated. The results show that shift, twist, lift and tilts displacements are detected to be rather uncritical and the system turns out to be rather stiff with respect to such displacements. The theoretical result is supported by the experiments and gives quantitive explanations why and how the capillary force works in the self-assembly process.

A theoretical investigation is performed into the problem of laminar filmwise condensation flow over a horizontal semicircular tube embedded in a porous medium and subject to capillary forces. The effects of the capillary force and gravity force on the condensation heat transfer performance are analyzed using an energy balance approach method. For analytical convenience, several dimensionless parameters are introduced, including the Jakob number Ja, Rayleigh number Ra, and capillary force parameter Boc. The resulting dimensionless governing equation is solved using the numerical shooting method to determine the effect of capillary forces on the condensate thickness. A capillary suction velocity can be obtained mathematically in the calculation process and indicates whether the gravity force is greater than the capillary force. It is shown that if the capillary force is greater than the condensate gravity force, the liquid condensate will be sucked into the two-phase zone. Under this condition, the condensate film thickness reduces and the heat transfer performance is correspondingly improved. Without considering the capillary force effects, the mean Nusselt number is also obtained in the present study as N u   ¯ | V 2 ∗ = 0 = 2 R a   D a / J a 1 / 2 ∫ 0 π 1 + cos   θ 1 / 2 d θ .
